This article describes the entire process of OSPF configuration from an experimental perspective, allowing you to deeply understand the process of configuring OSPF in the experiment.
Network Topology:
Purpose:
1. Start the OSPF routing process on the router;
2. Enable the excuse for participating in the routing protocol and advertise the network and the region where it is located;
3. Modify the reference bandwidth;
4. DR election control;
5. Broadcast OSPF features on multiple access links.

Cortex-A9 series Processors
Arm documentation set for ARM Cortex-A9 processor kernels, including arm Cortex-A9 mpcore and arm Cortex-A9 Single-core processors.
Arm Cortex-A9 processor is a very high-performance, low-power ARM macro unit, with L1 high-speed cache subsystem, providing full virtual memory functionality. The Cortex-A9 processor implements the ARMv7-A architecture and runs 32-bit arm instructions, 16-bit and 32-bit thumb instructions, and can also run 8-bit Java bytecode
VFP support code is still doing a lot of other things.Let's think about this:8374: ed1b7a05 FLDS S14, [FP, #-20]8378: ed5b7a04 FLDS S15, [FP, #-16]837c: ee677a27 fmuls S15, S14, S158380: ed4b7a05 fsts S15, [FP, #-20]8384: ed5b7a05 FLDS S15, [FP, #-20]We know that S14 and S15 are coprocessor registers and belong to the resources shared by all processes. So when the above example is executed to 0x8378, the program switches to another process, and this other process also accesses S14, then the res

Android-opencv is a transplanted version of opencv on Android phones, while cvcamera is a sample of this transplanted version. This document describes how to install and use Android-opencv.
Android-opencv Installation
Opencv is based on C ++, so Android-opencv must also rely on ndk (android-ndk-r4-crystax) to compile. PS: on the installation and use of android-ndk-
(r1 = 1 | S1 = 1) = P (R2 = 1 | S2 = 1) =... = 0.8, P (r1 = 0 | S1 = 0) = P (R2 = 0 | S2 = 0) =... = 0.8,
And P (s2 = 1 | S1 = 1) = P (S3 = 1 | S2 = 1) =... = 0.9, P (s2 = 0 | S1 = 0) = P (S3 = 0 | S2 = 0) =... = 0.9.
To make reasoning and computing easier, we will further convert it into a factor graph ). A factor chart is a undirected two-part graph. Some nodes represent variables and some nodes represent factors. Factor nodes connect nodes that may have probabilistic dependencies, this allow
keyword is C #, the master attribute is C #, and the non-master attribute is TN, ts, function dependencies are C # → TN, TN → ts. Because there is a dependency on C # ts for the transfer of candidate keywords by non-primary attributes in R2, the relational mode R2 is not 3nf.
The relationship R2 can be broken down into two 3nf relational modes without interrupting the connection:
P = {R3, R4}, R3 = {C #, tn}, r4

For the destination 192.168.1.0 and 172.16.1.4, router R2 receives the route advertised by its two neighboring routers R3 (10.1.1.3) and R4 (172.16.1.2) respectively. The shortest route to the destination 192.168.1.0 is through R3, the feasible distance is 20563200, but the advertised distance (281600) of R4 is smaller than th
The neighbor state machine after the mtu value of the H3C OSPF interface has been studying the OSPF principle and configuration of H3C over the past few days. Now there are two routers R3 and R4 connected through their respective Ethernet ports E0/0, after configuring the IP address and OSPF correctly, modify the mtu value of the R3 E0/0 interface to 1000 (1500 by default) and restart the OSPF process of R3, then R3 and
Recursive queries for routing are not necessary for dynamic routing in terms of static routes. The purpose of using recursive routing is to bypass those frequently changing links, which can reduce the configuration effort of static routes.First, the experimental topology650) this.width=650; "title=" image "style=" border-right-width:0px;background-image:none;border-bottom-width:0px; padding-top:0px;padding-left:0px;margin:0px;padding-right:0px;border-top-width:0px; "border=" 0 "alt=" image "src=
